To all whom t rofl/ay conc-ern:

Be it known that we, GEORG ENGELHARDL;

manufacturer, and a resident of Cassel, and

and foot-coverings arranged to permit of ob.

taining the proper position of the toe portion relative to the main orheel portion of the Wearers foot. y l

The invention consists of novel features and parts and combinationsofthe same, .as will be more fully'described hereinafter and then pointedout in theclaims.

, Practical embodiments ofthe invention are represented intheaccompanying drawings, .forming a part of this'specication', in'whichsimilar characters of reference indicate cor-A responding parts in allthe views.

Figure 1 is a facel view of the improvement `in the form of ameasuring-chart for determining the angular position of the toe portionrelative to the main foot portion. Fig. 2 is a plan View of theimprovement in the form 4of a measuring apparatus. Fig. 3 is across-section of the same on the line 3 3 of Fig. 2, and Fig.

4 is a longitudinal sectional elevation of the same on the line 4 4 ofFig. 2. l l

The chart shown in Fig. 1 is provided with a line a which.. forms aguide for the inner side of the foot, and at right angles to this .line,at kor near one endp thereof and beyond the point o, is arranged agraduated line Z e. extending on' both sides ofthe line a, b. v Both,sides of the line Z e have their graduation-` points marked alike byconsecutive numerals-was shown by the numerals 2 to 15 and from thepoint o extend radiallines to the points marked by the numerals on thegraduatedvline d e. The chart is also provided with v equidistant lines,marked .on each side of the chart by `a linear graduation Vindicatingthe f length of the foot from the backfof the heel lto thebeginning ofthe big toe, the,l graduation being in linear-measurement. units, suchas centimeters. In using this chart they footy is placed on the chart,as indicated in Fig.' :1f,-

. so `that the inner side of thefoot extends along' the line al), andtheback of the heel is placed on the transverse line indicating the length`of the foot from the back of theheel to the beginning of the 'big toe,forinstance, as shown in Fig. 1, on the line 40. When the radial lineextending from the point o to the graduated line 0l e is ktangential tothe big to'e of the foot, this line indicates the angular posiion of thebig toe to the main portion of the oot. Invpractice the chart ispreferably made of a transparent 'material-such as Celluloid,

Vtracing-cloth, and the like-'and in using the chart it may be ofadvantage for the shoemaker to rst obtain an outline drawing on a pieceof paperl of the foot and then place the same under the transparentchart, so as to `permit the Shoemaker to conveniently'btain the angularvposition of the toe portion relative tothe main portion of the foot.

If anumber of lasts for one series-say four lasts-areused in themanufacture of shoes and the like, the last is selected which agrees thenearest in the angular position of the toe portion relative to the mainfoot portion to the o ne obtained by the use of the chart.

In the apparatus shown in Figs. 2, 3', and 4a base 2.is'employed,.onwhich extends a lraised strip forming the guide 1, on which is mountedto slide a slide 3, abutting against r the back of the heelof the foot;the angular position ofthe big toe of which is to be 0btained relativeto the main foot portion. the top of the guide 1 are arranged twograduations 4 and 5, of which the graduation 4 indicatesthe entirelength of the foot in unit measurements and the graduation 5 in dicatesin the same units the length of the foot from the back of the heel tothe beginning of the big toe. A set-screw 7, which screws on theslide-3, serves to fasten the latter in position -on the correspondinggraduation-mark of the graduation 4 or 5, whichever is used at the time.In measuring the entire length of the foot use is made of astop 8 at theupper end 'of the guide 1, from which the graduation 4 is calculated, itbeing understood that the end `the back of the heel. When this has` beendone, the screw 7 is screwed up to fasten the vslide 3 in place, thecorresponding graduation Y.marked on the graduation .4 indicating thessl entire length of the foot, while the graduation on the scale 5indicates approximately the length of the foot from the back of the heelto the beginning of the big toe. At this point-that is, the beginningpoint of the big toe-is fulcrumed at 10 an arm 9 on each side of theguide 1, and each arm 9 when swung inward and outward is adapted tocoincide `with radial lines 11, extending from the axis of the pivot 10to a cross-line 2O 20, the points of intersection between the lines 11and 20 beingindicated by consecutive numerals 12 leading from the sideof the guide 1 outwardly, as plainly indicated in Fig. 2. When the footis placed on the base 2 so that the inner side of the foot rests againstthe corresponding side of the guide 1 and the arm 9 is swung against theside of the big toe, then the said arm indicates onY the correspondingnumeral on the graduated line 2O 2O the angular position of the toeportion relative to the main foot. It is understood that for the rightfoot the inner side thereof is abutted against the right side of theguide l, while the left foot is placed in position on the base 2, withthe inner side of this foot abutting against the left-hand side of theguide 1. In either ease, however, the foot is placed in such positionlon the base 2 that the beginning point of the big toe coincides with thepivot 10 for the corresponding arm 9. The slide 3 is provided withintegral sidewise-extending arms 13, on which are mounted to slidesidewise the offsets 14, adapted to be fastened by clamping-bolts 22 tothe arms 13, each clamping-bolt extending through an elongated slot 16,formed in the corresponding arm 13. By loosening the nut 15 for the bolt22 the offset 14 can be moved inward or outward on the arm 13, to bringthe forward 4curved edge 18 or' the ofset 14 against the back of theheel of the foot after the same has been placed in position on the base2 and the slide 3 has been moved up, as previously explained. The lowerend of the guide 1 is provided with a stop 19 to prevent the slide 3from accidentally leaving the guide 1 when the screw 7 is loosened. Inorder to prevent accidental movement of the arm 9 after the same hasbeen adjusted, a spring 29 is held on each arm, but in contact with theface of the base 2, to

` allow swinging movement of the arm by the operator and to hold the armin position after the same is adjusted. On the top of the base 2 isarranged a longitudinally extending guide-rod 23, having a tape 24 toallow of measuring the width of the foot across the ball thereof. Anumeral-table 26 is preferably arranged on the base 2 at one sidethereof, and this numeral-table is provided with a graduation indicatinga linear measurement corresponding to the graduation 4, and thegraduation is headed with the width of the foot, as indicated by thenumerals from 1 to 8, such as obtained by the use of the tape 24. Thepoint of intersection being obtained by following the column indicatinga certain width and the corresponding line for a certain length, theoperator obtains a iield for containing the number of the last for aparticular foot measure by the above-described deviee. The numberobtained for the last is indicated for a whole series of lasts,whichhave a different relation relative to the angle of the toe portionwith the main foot portion.

As the manufactured shoes contain the number of the last, it is evidentthat by the use of the device above described the size of the foot, aswell as width thereof, can be readily obtained in using the table 26. Inthe same manner models or patterns for other foot-covings-sueh asstockings, rubber shoes, and the like-can be readily made, and thearticles produced can be numbered according to the measurementsobtained.

We do not limit ourselves to the particular construction ofthe deviceabove described and shown, as the same may be varied without deviatingfrom the spirit of our invention.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1.
